Annual plant, a height of 60-80 cm. The flowers are collected in large terry floretses-basket, various colors. The petals are rolled up in a thin tube along the entire length. The diameter of the inflorescence is from 7 to 35 centimeters. Flowers are abundant and long, very decorative in flowerbeds, slaves and large flower massifs. Require sunny, protected from cold and strong winds places with good air circulation. Should not be planted on low and marshy areas. They are afraid of even slight frosts. Blossom in 80 days after the emergence of seedlings.
How to Plant Dahlia Seeds
It can take a full season for you to see flowers on your seeded dahlias. Do dahlia seeds turn into tubers? In the first year, slender tubers will form but they will not be anything worth harvesting and will need another year or two to develop good growth nodes and produce bodacious plants. The first step to starting dahlia seeds is harvesting ripe, ready pods. Pods contain numerous seeds. Wait until the flower has dropped all its ray petals and the pod is a light tan-green color. The seeds inside should be ripe and gray to dark brown. Cut the pod off and let it dry to facilitate removal of the seeds. Separate the seed from the rest of the pod and allow let dry before storing. In early spring, germinate the seeds in soilless seed starting mixture in flats. Sow your seeds an inch (2.5 cm.) apart on the surface of the mixture and cover lightly with a dusting of the medium. Moisten the medium and keep moderately damp, moving the flats to a warm location of at least 70 degrees F. (21 C.). Germination will occur in 7 to 12 days after sowing. Once the seedlings are large enough that their leaves are touching, individually pot them up in 3-inch containers. Harden the seedlings off before planting them out into prepared garden beds. Wait to plant them outdoors until all danger of frost has passed. Alternatively, you can plant them outdoors a week before the date of the last frost. In northern climates this may not give the plants enough time to develop and bloom. It works great in long season areas, however. If cold temperatures threaten at the end of summer, repot the plants and move them into a greenhouse or indoors. They won’t have much tuber development, and the best way to save them for next season is to let them go dormant indoors where icy temperatures can’t damage the tiny root and tuber system. Harden them off the next season and plant outdoors. You will get big beautiful plants with plenty of appealing flowers that will set pods and start the whole growing dahlia seeds process over anew.
